`event_timestamp_column: [column name]`

Configuration for the test `event_freshness_anomalies`.
This test compliments the freshness_anomalies test and is primarily intended for data that is updated in a continuous / streaming fashion.

The test can work in a couple of modes:

- If only an event_timestamp_column is supplied, the test measures over time the difference between the current timestamp (“now”) and the most recent event timestamp.
- If both an event_timestamp_column and an update_timestamp_column are provided, the test will measure over time the difference between these two columns.

- _Default: None_
- _Relevant tests: `event_freshness_anomalies`_
- _Configuration level: test_
